All flames aside.
The big risk in over-filling the crankcase is oil cavitation. The oil level being high enough that the crankshaft moving through the oil like an egg-beater whips air into the oil and makes it froth. The resulting damage may not be realized for a long time as the primary path of the oil is to the crank bearings first. If any damage was done, you would not know without a tear-down or until pre-mature bearing failure, which may not occur until twenty or thirty thousand miles.
Sorry to rain on anyones parade.
